I’m trying to refresh a Power BI dataset using Azure Synapse’s web activity by making a POST request as detailed in this [tutorial](https://www.tackytech.blog/how-to-refresh-power-bi-datasets-from-data-factory-with-managed-identity/. However, I’m encountering an “ItemNotFound” error despite following the instructions closely.

{
  "errorCode": "2108",
  "message": "{"error":{"code":"ItemNotFound","message":"Dataset xxxxxxx is not found! Please verify datasetId is correct and user have sufficient permissions."}}",
  "failureType": "UserError",
  "target": "Web1"
}

Steps I’ve followed:

• Configured the managed identity in Azure Synapse.
• Configured Powerbi Tenant settings.
  [
• Set up the web activity to use the POST method with the URL for dataset refresh.
• Verified dataset ID and permissions.

Despite these steps, the dataset refresh fails with the above error. Could anyone help me understand what might be going wrong here or if there are additional settings I need to verify?
